Just got my new Kindle Fire HD 8 Plus today and downloaded BOINC from the Amazon app store. When I try to add Science United as my account manager which I also use on my MacbookAir, the app just spins saying Add Account for over an hour with no error. If you change the orientation of the screen, it cancels the add request. I don't see a problem with network connectivity and if I choose a different account manager, I immediately get an error that my account does not exist from that account manager. I've also tried connecting to a hotspot via my iPhone with no different results. Any helpful suggestions of where to look next? Thank you in advance! Hopefully setup on a raspberry pi 4 goes smoother next week.
